I remember in San Francisco back in the mid-60s, there was a version of "Pick A Show" on KRON, which back then was an NBC Affiliate. The game was hosted by Art Finley, who earlier on KRON was best known as "Mayor Art", which was a children's show.
And yes, the game had a few levels and the player had to guess where the call letters were on each level, then after successfully getting all the call letters, the contestant (All were phone contestants) had to choose where the station number was behind six to eight panels. If that person found the station number, that person would win the grand prize.
It was a simple game which lasted almost a year, as I recall, but it was a fun show.
